Project Title Development of Scalable User Login, Private Storage, and Sharing Features for Flutter App Project Description We are looking for an experienced developer/team to work on the second phase of our Flutter app. The app is already functional for a single user, but we now need to make it scalable and enhance its features to support multiple users with private storage, secure login, and sharing capabilities. Key Objectives: User Management: Implement a secure login and authentication system (e.g., AWS Cognito, Firebase Authentication, or OAuth2). Create user profiles with customizable details (name, photo, preferences). Ensure complete isolation of user data. Private Storage & Sharing: Integrate AWS S3 for private image and listing storage per user. Enable secure sharing of images and listings with other users via search. Implement role-based access controls (user will have ability to make uploaded pictures/listings public for sharing with the other users on the app or private). Develop a search feature for users to browse public listings. Facebook Login Automation: Enhance Selenium-based Facebook integration to allow multiple users to automate actions independently. Use browser profiles or other methods to securely manage Facebook logins for each user. App Optimization: Polish the existing app for improved performance and usability. Ensure smooth transitions between new and existing features. Deliverables: Fully functional multi-user login and authentication system. Scalable private storage integrated with AWS S3. Sharing functionality with access controls. Public listing and search capabilities. Secure and scalable Facebook login automation. Optimized and polished Flutter app ready for multi-user deployment. Technical Requirements: Backend: Flask (existing), AWS Lambda (optional for serverless). Database: DynamoDB (preferred), or other scalable solutions. Storage: AWS S3 for media and listings. Frontend: Flutter. Authentication: AWS Cognito or Firebase Authentication. Expectations: Strong expertise in Flutter app development. Experience with AWS services (S3, Cognito, DynamoDB) and Selenium. Ability to write clean, scalable, and secure code. Clear communication and regular updates. Post-delivery support for bug fixes and minor adjustments.
